METALLIC RAILWAY CBOSSTIE AND RAIL-FASTENING.

Original application filed December 1, 1916, Serial No. 134,322.

1917, Serial No. 159,203. Renewed T 0 all whom it may concern:

Be it known that we, OTTO J. BosrnoM, EDWARD E. WVALTMAN, and RUDOLPH F.ZINGsI-IEIM, citizens of the United States, re siding at Rawlins, in thecounty of Carbon and State of lVyoming, have invented certain new anduseful Improvements in Metallic Railway Crossties and Rail-Fastenings,of which the following is a specification.

This invention relates to new and useful improvements in metallicrailway cross ties and is a division of our application for metallicrailway cross ties and rail fastenings, tiled December 1, 1916, Ser. No.134,322. r

The object of our invention is to provide an improved form of cross tiehaving a free movement or cushioning effect under each rail.

lVith the foregoing and other objects in view that will appear as thenature of the invention is better understood, the same consists in thenovel features of construction, combination and arrangement of partsillustrated in the drawings and more particularly pointed out in theappended claims.

In the accompanying drawings Figure 1 is a side elevation of a metallicrailway cross tie embodying our improvements, the rail fastening meansand the' rails being also shown.

Fig. 2 is a plan view of Fig. 1.

Fig. 3 is a detail fragmentary sectional view of a portion of one end ofthe tie and the adjacent rail fastening means with the parts shown on anenlarged scale.

Fig. 4 is a detail sectional view taken through one of the keepers, itsadjusting screw and associated parts. Fig. 5 is a bottom plan view ofone of the rail fastening plates.

Fig. 6 is a plan view of one end of the cross tie.

Fig. 7 is a transverse section taken on line 77 of Fig. 6, looking inthe direction indicated by the arrows.

Fig. 8 is a similar view, looking in the opposite direction as indicatedby the arrows.

Specification of Letters Patent.

Divided and this application filed April 2, July 26, 1920. Serial No.399,177.

10 is a detail perspective view of the connecting rod.

Referring to the drawings for a more particular description of theinvention, 1 indicates the metallic cross tie, 2 the rails, 3 the railfastening plates and A a connecting rod employed at the center of thetie, the purpose of which will be presently disclosed. The metalliccross tie comprises the flat approximately rectangular oblong baseportions t which are formed at opposite ends thereof and are connectedby the relatively narrow web or strip 5 at the center of the tie. Thetie is also provided at each end with a flat top portion 6 whichportions are supported upon and above said base portions 4 by thevertical legs 7 and the central longitudinal webs or ribs 8 which arecut away for the greater part of their width at the center of the tie,as at 9, and connected together by the movable connecting rod A abovementioned, the outer bifurcated ends 12 of the two sections a and Z) ofwhich are loosely connected with the inner end portions 10 of said webor ribs by the cross pins 11. The fiat top portion 6 at each end of thecross tie which forms a support for the rail is provided at oppositeends and at diagonally opposite points with the longitudinal slots 13and the vertical apertures 14; which are spaced inwardly of said slotsand are arranged in longitudinal alinement therewith.

The rail fastening plates 3 which are of substantially triangular form,are recessed or cut away at their inner ends, as at 15, to receive thebase of the rails and are provided at their outer ends with thedepending portions or extensions 16 which project through and below andwork in the longitudinal slots 13 in the top portions 6 of the rail andhold them against any rotary or turning movement when in normal positionor when moved in either direction, to engage or disengage the rails. Therail fastening plates, as shown, are provided with the centrallongitudinal slots 17 through which pass the bolts 18, which areinserted through the vertical apertures 14 in the top portions of thecross tie with their heads fitting against the bottom faces of said topportions and their upper threaded ends projecting above the tops of thefastening plates to receive the nuts 19 which are screwed against the 22in the upper ends of the keepers 23, theinner ends of said adjustingscrews bearing against the outer ends or heels of the fastenlng plates.As shown, the keepers 23 are provided with reduced central portions 24which pass through the slots 13 and fit against the outer end wallsthereof and are also orovided at their lower ends with heads 25 w ichextend across the slotted portions 13 of the top members 6 of the crosstie and fit against the bottom faces thereof whereby the keepers areheld in position.

The cross tie may be increased or decreased proportionately in lengthand other dimensions, making it suitable to wide or narrow gage track inorder that it may support either heavy or light equipment according totrafiic conditions as used in modern railways. It is also pointed outthat the form of rod A and the tie shown permits the latter to have afree movement or cushioning and resilient effect on each rail. WViththis end in view, one section, as a of said rod is provided at its innerend with a fork 0 which receives the inner end of the other section b ofthe rod. A coil or helical spring (Z is disposed around the forked endof section a and bearing against the outer end of said spring is anoblong washer or plate 6 which is formed with a central transverseaperture c to receive the inner end of rod section b and works betweenthe two tines or members of the fork 0 of rod section a. A nut isscrewed on the inner end of rod section 6 to secure the latter in placewhile the inner ends of the tines 0 of rod section a are formed withoutwardly bent lugs or hooks g to hold the coil spring in place.

From the foregoing, it will be seen that in view of the yieldingconnection between the inner ends ofthe rod sections a and b, the rod 'Adoes not'interfere with the resilient or cushioning action of the crosstie under the rails while the coil spring facili tates the return of thetie to normal position after the train has passed, under which con--ditions the rod A provides a reinforcement for the central cut-awayportion of the tie. Having described our invention, what we claim as newand desire to secure by Letters Patent, is

In combination, a metallic cross tie having a flat base and flat topportions at opposite ends thereof, supported upon and above the base byvertical legs and a central upright longitudinally disposed web, saidweb being cut away for the greater part of its width between the topportions of the tie and a connecting rod loosely connected at oppositeends with the inner ends of said top portions, said rod comprising twosections slidably connected together at their inner ends.

In testimony whereof we aflix oursignatures in the presence of twowitnesses.
